Go to SETTINGS → CALIBRATE and tap to the metronome — the game suggests an offset automatically (it also auto-compensates for your device's audio latency on first launch). Bluetooth headphones add latency; calibrate with the headphones you actually play with.
SETTINGS → NOTE SPEED adjusts the approach speed. It changes visual lead time only — judgment timing is unaffected.
The game is fully playable offline. Network access is used only to load an occasional ad after a song's result screen — never during gameplay. Ads are always non-personalized, and the app never tracks you (you will never see a tracking permission prompt). See the Privacy Policy for details.
On your device only. There is no cloud sync yet — deleting the app or switching phones resets your scores.
Tap "? HOW TO PLAY" next to PLAY on the main menu to reopen the tutorial cards and the practice stage anytime.
That's intentional — every track has its own key and timbre, and your hits are tuned to it. Cleaner timing also makes the tone ring brighter.
